sequelize js with big integers

问题

I have an application written in Node JS and uses the Sequelize js ORM library to access my database which is MySql.

My problem is that I have a column in my db which is BIGINT and when the value of it is large I get wrong values when I retrieve it.

for example when the value in database is: 10205918797953057 I get 10205918797953056 when I get it using sequelize.

I tried using big-integer library but I had no luck.

any advice is welcomed.

P.S: I can't change the datatype to VARCHAR.

You should enable supportBigNumbers and possibly bigNumberStrings on the mysql module: https://github.com/felixge/node-mysql#connection-options

new Sequelize(..., {
  dialect: 'mysql',
  dialectOptions: {
    supportBigNumbers: true
  }
});
